DRAWING- INSTRUTEENT.

Application filed July 23, 1920. Serial No. 398,375.

To all whom it may concern:

Be it known that I, FRANK C. Kin-lane, a citizen of the United States, residing at Chi.- cago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Drawing Instruments, of which the following is a specification.

This invention relates to drawing instruments, and comprehends the provision of a device by means of which spaced parallel lines may be simultaneously drawn, and the distance between the lines regulated or varied, the invention being primarily intended for use in drawing guide lines in pencil for lettering purposes.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the invention residing in the construction, com bination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a side elevation of the instruments forming the subject matter of my in vention.

Figure 2 is an edge elevation.

Figure 3 is a sectional view taken on line 33 of Figure 1.

Figure 4 is a perspective view of one of the lead holders.

The instrument forming the subject matter of my invention embodies a metal forked like member indicated generally at A, the latter being formed to provide a sleeve like portion. 10 to accommodate a handle 11 of any suitable material and length. The memher also includes the spaced limbs at 12 which are connected together by an adjusting element 13 and through the instrumentality of which the limbs may be moved toward and away from each other when the occasion requires. The limbs 12 are slightly converged as shown, and associated with the outer end of each limb is a lead holder 14. These holders may be constructed from any suitable material and also vary in size without departing from the spirit of the invention, each member having a longitudinal bore 15 opening at both ends of the member, and also at one side thereof defining a longitudinal slot 16. The bore 15 of each memher is of sutficient diameter to receive a piece of lead 17 the latter being held in the members by friction. One end of the piece of lead can be projected beyond this member,

from time to time by inserting a suitable instrument in the slot at 16 and pressing against the lead in one direction. The construction is such that spaced parallel lines can be simultaneously drawn, and the distances between the lines easily regulated,

the instrument as above stated being primarily designed for drawing guide lines for lettering purpose on drawings.

While it is believed that from the fore going description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to the details herein shown and described and that such change may be resorted to when desired as falls within the scope of what is claimed.

What I claim is:

An instrument of the character described including a handle, a sleeve-like member fitted on one end of the handle, spaced limbs so integral with and projecting from one ond. of the sleeve, an adjusting screw connecting said limbs whereby the latter may be ad justed toward and away from. each other,

lead holder carried by the outer side of each
